Edward Anhalt, the writer of this movie was an experienced writer and he wrote more than 40 movies. Stanley kramer adapted the script to an interesting movie about the medical world; most details are right and Frank Sinatra and Robert Mitchum (dr. Lucas Marsh) deliver an outstanding performance. Dr. Marsh is Robert Mitchum and vice versa. A doctor like him is rare nowadays but they still exist. His passion for truth makes dr. Marsh vulnerable but at the same time it is also his strength.
